Patent DE-2730064-A1 (DE)
Inventor: DIEHL ERWIN DR
IPC: C23C2/30
Filed: 1977-07-02
Abstract: The invention relates to a process for wet-galvanising objects which essentially consist of iron. The purpose of the invention is to provide an economical process for wet-galvanising metal objects without the formation of troublesome ammonium chloride mists, and also to combine the advantages of wet-galvanising with those of dry-galvanising. According to the process of the invention, wet-galvanising is effected by first applying to the zinc melt a salt mixture which consists of zinc chloride and potassium chloride in weight ratios of from 95:5 to 70:30, and after the salt mixture has melted, placing onto the melt compacts, which consist of ammonium chloride and potassium chloride in a weight ratio of from 70:30 to 90:10, in such an amount that the concentration of the ammonium chloride in the melt is at most 5% by weight, this concentration being maintained during the following galvanising treatment by occasional further addition of ammonium chloride/potassium chloride compacts having the abovementioned composition.

Title: Echo signal ultrasonic diagnostic appts. - uses processing circuit with sectional memory and scanning system between two converters
Inventor: HEITMANN JUERGEN
IPC: A61B8/00
Filed: 1978-03-17
Abstract: The ultrasonic diagnostic apparatus using echo signals to obtain a display on the screen of a CRT, uses a parabolic reflector.

Title: Carbon mon:oxide and hydrogen recovery from gas mixt. - by partial liquefaction, rectification and scrubbing with liquid nitrogen
Inventor: FABIAN RAINER DIPL ING
IPC: F25J3/02
Filed: 1978-04-05
Abstract: Recovery of CO and H2 from gases contg. these and other constituents (CH4, Ar, N2 or C2H6) involves cooling under pressure, partial liquefaction, rectification and scrubbing. The gaseous fraction left after partial liquefaction is transferred to a scrubber operating with liquid N2, H2 being taken from the top, whilst (pt. of) the liquefied fraction is passed to a one-stage rectifier. The top fraction from the rectifier and (pt. of) the sump fraction with the N2 scrubber are passed to the high pressure zone of a double rectifier and the top fraction from this zone is passed into the low pressure zone, where CO is withdrawn from the sump. The claims also cover the equipment used. CO and H2 can be recovered from gases of widely varying compsn., as well as cracked gas from a steam reformer. H2 can be obtd. in different purities at different levels of the scrubber, e.g. very pure H2 suitable for butanol synthesis and less pure H2 and NH3 synthesis.

Title: Up-grading periodic signals - using comparator causing selector logic to block switch to reference register if signal periods lie outside stipulated tolerances
Inventor: BAUR ANTON DIPL ING
IPC: G01R19/00
Filed: 1978-11-18
Abstract: Circuitry for up-grading periodic signals has a comparator stage for each pair of sequential signal periods. This stage ascertains if the periods match within stipulated tolerances. A selector logic responds as soon as an adjustable number of sequential signal periods is deemed to lie within the tolerances so that all following corresponding signal periods are switched to a reference register as long as they also lie within the stipulated tolerances. A counter in the form of a digital oscillator is connected to this reference register. This counter is fed with the intermediately stored information in the register during the time of the latest received signal periods. The counting rhythm is identical to the signal frequency but is independent w.r.t. phase.
